A powertrain includes an electric machine including a rotor defining a hollow center and a fluid-coupling assembly at least partially disposed within the hollow center. The fluid-coupling assembly includes an input shaft, a turbine fixedly coupled to the rotor and having a hub configured to connect with a transmission input shaft, and an impeller configured to fluid couple with the turbine. The impeller is selectively coupled to the rotor and selectively coupled to the input shaft.

A multi-mode hybrid module includes a fluid coupling, an electric motor and a first clutch. The fluid coupling includes a fluid coupling housing, an impeller drivingly connected to the fluid coupling housing, and a turbine arranged for driving connection to a transmission input shaft. The electric motor includes a nonrotatable stator and a rotatable rotor including a rotor carrier. The first clutch is arranged to drivingly connect the rotor carrier directly to the transmission input shaft. In some example embodiments, the first clutch is a dog clutch. In some example embodiments, the multi-mode hybrid module includes a first clutch actuator. The first clutch has an axially slidable sleeve arranged to selectively rotationally connect the rotor carrier and the transmission input shaft, and the first clutch actuator is arranged to displace the axially slidable sleeve to connect and disconnect the rotor carrier and the transmission input shaft.

An example includes a hydraulically controllable coupling to couple a rotating input and to an output to rotate, or to decouple the input and the output, with coupling and decoupling modes selected by switching a hydraulic device such as a vane pump between a pumping mode and a mode in which it does not pump. In an example, the system cooperates with a transmission to increase the number of possible gear ratios in some examples.

A torque damper apparatus including an input plate, an intermediate plate, an output plate, and a spring member interposed between the intermediate plate and the output plate so that the torque transmitted from the intermediate plate to the output plate is reduced. The output plate includes a pair of plates arranged so as to separate from each other in an axial direction and a fastening part fastening the pair of plates. The spring member is a coiled spring arranged along a circumferential direction about the axial line, and the intermediate plate includes a holding portion holding an inner end of the spring member in a radial direction about the axial line, and a plate portion extended from the holding portion toward an inside in the radial direction between the pair of plates and supported rotatably relative to the fastening part.

A device for filling a hydrodynamic coupling with operating fluid and a method for filling a constantly filled hydrodynamic coupling during commissioning and/or for checking or setting a fill level with operating fluid. The device and the method provide the use of image recognition, by way of which an inspection window can be recognized and by way of which a position of the inspection window can be set.
